Wake development behind paired wings with tip and root trailing vortices: consequences for animal flight force estimates. [PDF]

open access: yesPLoS ONE, 2014
Recent experiments on flapping flight in animals have shown that a variety of unrelated species shed a wake behind left and right wings consisting of both tip and root vortices.

Detecting wing fractures in chickens using deep learning, photographs and computed tomography scanning [PDF]

open access: yesPoultry Science
Animal welfare monitoring is a key part of veterinary surveillance in every poultry slaughterhouse. Among the animal welfare indicators routinely inspected, the prevalence of wing fractures and soft tissues injuries (e.g.

Biocompatibility and biosafety of butterfly wings for the clinical use of tissue-engineered nerve grafts

open access: yesNeural Regeneration Research, 2021
In a previous study, we used natural butterfly wings as a cell growth matrix for tissue engineering materials and found that the surface of different butterfly wings had different ultramicrostructures, which can affect the qualitative growth of cells and

How the monarch got its spots: Long-distance migration selects for larger white spots on monarch butterfly wings.

open access: yesPLoS ONE, 2023
Elucidating the adaptations that promote flight in animals can aid the understanding of evolution and species divergence, and/or provide inspiration for aerospace engineering and the design of better aerial vehicles.

Animal-Based Measures for the On-Farm Welfare Assessment of Geese

open access: yesAnimals, 2020
Currently, no specific animal-based measures (ABMs) protocols are available for geese in commercial meat production systems. Following a critical review of the literature and consultation of experts, seven ABMs, potentially valid and feasible for the on ...

The Beast Within, the Beast Without

open access: yesVenezia Arti, 2023
Drawing on and accentuating classical motifs, the surfaces of Renaissance armour are inhabited by an impressive variety of animal exuviae: leonine protomes and paws, ram’s horns, shells, tails, beaks, and wings.

On the autorotation of animal wings [PDF]

open access: yesJournal of The Royal Society Interface, 2017
Botanical samaras spin about their centre of mass and create vertical aerodynamic forces which slow their rate of descent. Descending autorotation of animal wings, however, has never been documented. We report here that isolated wings from Anna's hummingbirds, and also from 10 species of insects, can stably autorotate and achieve descent speeds and ...

Deep learning approaches to landmark detection in tsetse wing images.

open access: yesPLoS Computational Biology, 2023
Morphometric analysis of wings has been suggested for identifying and controlling isolated populations of tsetse (Glossina spp), vectors of human and animal trypanosomiasis in Africa.

Dissection of Larval and Pupal Wings of Bicyclus anynana Butterflies

open access: yesMethods and Protocols, 2020
The colorful wings of butterflies are emerging as model systems for evolutionary and developmental studies. Some of these studies focus on localizing gene transcripts and proteins in wings at the larval and pupal stages using techniques such as ...
